1'0 all whom i; may cmtccrni;

Be itknown that I, J ULES Pamnoo'r, paper manufacturer, a citizen of the Republic of France, residing at'Arches, in the Departmentof Vosges, in the Republic of France, have invented certain new and useful Improvements in Paper-Making Machines, (for which application has been made in France, No. 337,911,

.December 21, -1 903; Germany, December 29, 1903; England,No. 25,726, November 25, 1904;

Belgium, November 28, 1904, and Switzerland, November 28, 1904,) of which the following is a specification.

This invention has for its ob ect improve ments in continuous paper-making machines,-

' affording meansfor avoid ingany deformation of the sheet and any alteration in the felting of the fibers. In fact, in order to avoid any deformation of the paper sheet it is necessary that, first, the supporting band or belt should be practically non deformable; second, the

.sheet should only leave the supporting band or apro'n whenit is completely dry. The present invention realizes. these two conditions by adopting as support a fine very resistant metallic cloth or band, which carries the sheet of paper through all the drying operation.

The accompanying drawings show a diagrammaticsketch intended to explain how the invention isput in practice in a continuous Figure 1 shows diagrammatically the draining, transferring, and drying apparatus' for Fig. 2'rcprcsents in dia- The layer of pulp drains, as in all papermachines, through an endless metallic-cloth belt 1. \Vhen it has reached the end of this band or belt, the layer of pulp forming a sheet a is pressed by a drum 2, surrounded with. felt 3, on which the sheet adheres. The felt 3 is stretched and guided by a series of rollers 4' in theordinary manner. Above the drum-2' a pressing-roller 5, surrounded by a metallic cloth or band 6, is placed, which band will accompany the sheet of paper through all the drying operation. It is-well not to make the sheet a pass directly fromv the mctallic'cloth 1 on to the metallic cloth 6, first, because the sheet directly compressed-between these two cloths would retain their impression and would. undergo too strong a pressure, and, secondly,

bcca'usedt'wopld Ice-detached with diliiculty from-one of the metallic cloths in order to Specification of Letters Patent. Application filed December 14, 1904. Serial No. 236,874.

pass on to theT other. On the contrary, loy in terposing a felt-coated drum 2tl1e sheet a felt 3 and from the felt 3 onto the metallic cloth 6. There is no need ,'to fear that the sheet wilhsuifer in' its passageover the felt 3,

on the drum 2 and between the two. points of contact with pressure-rollers o and 5.- The felt 3 may, however, be dispensed with and re' placed by a'sleeve on the drum 2. Itis in or'-' "der to facilitate the cleaning .'.of said sleeve that it is preferable to replace the 'sleeveiby afelt fulfilling the same object. 1 I

On quitting the roller 5 the sheet 9, &c.' In its passage over thefi'rst'dryingcloth shall'be interpolated between the sheet turn over small sleeved rollers- 20. Afterward'the sheet of paper and'the-metal'lic cloth are alteruately in contact with the dryingcylinders, and the arrangements are made in 5 such away that the sheet is in direct contact,

with the last drying cylinder n-cylinders 10,- from-whence it is wound on a reelIl. The metallic belt, guidedby small rollers 12, re -turns t the roller5 aftehbeingpassed' through -stretching devices,'belt-'gnides,. cleaaing appliances, and the like.
